Swansea led from the 11th to the 88th minute on a dramatic night at the Liberty Stadium.

Spurs' title hopes looked over, but Dele Alli equalised and Son Heung-min and Christian Eriksen struck in stoppage time to secure a fifth straight league win.

"Chelsea is looking very strong but we can't stop pushing and dreaming of the league," Belgium defender Vertonghen said.

"They had a big win (2-1 against Manchester City) but they have a couple of difficult games coming up. We have to keep winning and hopefully they get a bit stressed."

Tottenham, who face Watford at White Hart Lane tomorrow, added: "I don't know what is necessary to win the league - maybe a bit of luck - but I think this group has massive quality and is very special."
